Referring to the drawings, a camp stove ot the collapsible type is disclosed which comprises the stove containing casing 11 in the upper parts of which is disposed a grid 12 hinged at its rear sides with lugs or clips 13 secured to the rear of the casing 11. The casing 11 has a stove secured therein with the burners i disposed below grid 12. The casing 11 is supported on legs 14 which swing about the pivot arms i-l journaled in clip brackets 15 secured to the bottom of casing 11. and which have curved arms 14-" adapted to extend through holes 11 in the bottom of casing 11 adjacent the sides thereof whereby the legs it may be swung into the casing, as shown in Fig. 1, or may be extended to support the casing, as shown in Fig. 2, said curved arms 14 having notches 1s adjacent one end adapted to snap into engagement with the sides of the holes 11*, said arms being resilient so that they can be readily disengaged. The casing 11 is provided on one side with a swinging bail handle 11 by which the device is carried when in collapsed condition.

portions l1 01" the casing extending therearound. The plate 16 is shown as having);

its edges 16 folded inward to term a bead, which head is slotted at spaced points to provide spaced pintles about which extend at the ends oi? said plate the ears 19 secured to rectangular plates 19, which latter plates are thus hinged. at each end of plate lb, said plates 19 being shown as having; their upper and lower edges l9 folded inwardly. The plates 19 are provided with a row of holes 19 adjacent their lower edges, which term draft holes and certain of which are used if r a. purpose to be later described. The plates 19 also have pivoted to their outer sides adjacent their upper corners flat bars or rods 28, which bars or rods may be swung; into the position shown in 3 and 5. The plate 16 has spaced ll? secured thereto at its outer longitudinal edge which extend through slots termed in the edge of a plate .20 also 01" rectangular shape and of substantially the same length as plate 16. which plate 20 has an inwardly extending flange 20 oil con'iparatively sniall heightextending across its ends. The outer edge of plate 20 is provided with spaced slots 20" through which extend the substantially cylindrixal ears 21 which als extend through slots -tornied in a strip Another rectangular plate 2 L has slots 24-, formed in its inner edge corresponding to the slots 20 and substantially cylindrical ears or clips 23 extend tlllOUji'll the slots 2 i and through the slots 22 in the strip The plate 2% also has inwardly extending; flanges 524i" at each end and said plate is illustrated as ha vinp; its front edge rolled inward over a wire and slotted at its central portion to receive an operating; handle tongue 25. Plate 24. also has secured l'ieret-hrough substantially n'iidway thereof} downwardly extending clips 28 which are somewhat resilient and adi-ipted to co-operate when the device is in collapsed condition with pins 2"? projecting from the ends t casing 11. Pins 27 are carried at the upper ends of resilient strips 28 secured at their lower ends to the inside out casing 11. The casing 11. has a bracket 29 secured at each end provided with spaced ears in which journaled a rod 30 the lower end 30 of which is bent at a right angle andthe upper end 80 of which neeeyoas is also bent at a right angle and termed with hook 30 at its outer end. The rods 30 can be lifted in brackets 29 and swung outwardly across the top of the casing, as in dicated in dotted lines in F 6, and as shown in Fig. a, said rots, when the wind shield is not in use being disposed as shown in Fig. 6. The casing also has pivoted at its end a fiat strip 31 having a tongue 31 cut and struck up therefrom on its inner side.

A heat distributing plate $32 is provided made from a rectangular piece oi sheet metal having its longitudinal ed; as" bent downwardly and somewhat inwardly and proridel'l along .its ends with rows of holes 32. {laid plate also has ears 32 cut therefrom and bent downwardly in spaced relation adjacent each end thereot and these cars have pivoted therein at each end of the plate, a bail 23; formed from a small rod or wire these hails carrying on their lower portion, spaced ears as secured to a smaller rectangular plate 34:. ihe plates and 34- are thus pivotally' connected for relative swinging movement, as indicated in Fig. 9.

When the device is in collapsed coiulition the parts are disposed as shown in Figs. 1 and 7. The plates 1%) are 'lfoldcd inwardly in overlapping relation against the inner side o'l plate 16, the bars 28 at this time being, in the position shown in Fig. 2 relative to plate 19. The plates 13) and iii are then it'olded about the pintle rod l7 down onto the grid 12. Plate 20 is then folded down on top of plate 16, said plate extending rearwardly, as indicated in Fig. 2 and as shown in Fig. 7. The plate then folded torwardly and down on top of plate 20. The flanges and B l-. together with the strip 222 will now form the sides oi a subst *iriall'y closed. chan'iber, the bottom ot which torined by plate 20 and the top by plate 2%. The distributing plate 32 is swunpdown or in close relation to the plate 34: and these plates are disposed in said closed chan'iber, as shown in Fig. 7. The parts are thus very neatly and. compactly tolded down on the casing 11 and grid 12 and occupy very small space. The clips 26 can now be engaged over the pins 27 and will. owing to their resiliency, remain in engagement with said pins. The casing and collapsed oren can thus be easily transported and may be carried by the handle 11.

lVhen it is desired to use the oven for baking purposes, the clips 26 will be sprung and released pins 27 being pushed inwardly. The plate will be swung upwardly from grid 11 about pintle 1?. The grid 12 will now be lifted and strips 31 swung to vertical position, as indicated in dotted lines in Fig. 6. It may be mentioned that the strips 31 when in vertical position rest against the inner side of the flange 11 on which the grid 12 rests. The plates 19 are now swung outwardly and slightly raised and then lowered with their edges between strips 31 and tongues 31. The plate 16 will now be held in vertical position and plate 20 will be swung over the plates l6 and 19, the tlanges 2t) extending alon the outer sides of plates l9. The plate Q-l will now depend atthe front of plate :30 and the [hing s 24 will extend along the outer iront sides of the plates 19. A. closed rectangular ove thus formed which is disposed over and supported on the casing 11. The stove in casing ll comprises lnirners 12 below grid 12 and in order to distribute the flame lrom these burners evenly the device shown in Fig. 8 is placed in the oven. Plate rests on grid 12 and plate 232 hits snugly between the plates 19 so that it is held in vertically spaced relation to the plate Zl-l, the bail members 33 being substantially vertical. "he oven can now be. used :i'or baking any kind of baked articles and a very ellicient oven is provided. It will be noted that the plate 24 can be swung upwardly and rearwardly on top of plate 20 so that the front of the oven may be left open. This is sometimes desirable when it is merely wished to warm up certain articles of food, and plate 24: then forms a convenient shell on top ol' the oven.

If it is desired to use the oven as a warn1- ing oven, the same can he swung rearvmrd bodily about rod 17 and the bars 28 swung down to contact the su piporting surface. as shown in Fig. A convenient warming cabinet or oven is thus formed and articles may be set on top of the same which is formed by plate 2-1-. If desired, the plates 20 and may be folded rearwardly into the position indicated in dotted lines in Fig. 5. the plate 20 being then supported .in hori- ;aontal position by the plate 2-1:, the latter acti'ng as a leg. A wide shell is thus formed which may be used to su iport various articles used in preparing a meal.

ll it is desired to use a wind shield with the stove, which is often necessary when there is considerable wind, the rods 30 are lit'tedv and swung outwardly, as shown in Figs. l and 6. The plates ll) are then swung outwardly in diverging relation, as shown in Fig. land hooks 3t)" engaged through the holes 19, as shown in l ig. -Il-. Plates l9 and 16 are thus held in vertical position and an ellicicnt wind shield is provided for the stove. When the parts are in the position shown in Fig. l-. the plates 20 and 2st merely hang down in the rear of plate 16. It should be particularly notec that plates 16, 20 and 2 are connected by a double hinge. that is, these plates can swing substantially through 360 degrees. The plate 20 can thus be tl olded backwardly when it is disposed in its collapsed position, and, as stated, plate 2st can be folded back on top of the oven. As before stated, the members 30 and ill swing inside of casing 11 when the device is in collapsed and packed condition.

From the above description it is seen that applicant has provided an extremely simple and etlicient oven structure for a folding camp stove. The device can easily and quickly be arranged in a plurality of positions, each of which has great utility and the whole device can be easily and quickly collapsed into small space and arranged for transportation. The device is quite simple and easily made from simple material which is readily procured. The device has been amply den'ionstrated in actual practice and found to be very successful and ellicient and the same is being commercially madeand marketed.

ll; will, of course, be understood, that various changes n'iay be made in the form, details, arrangement and proportions of the parts without departing from the scope or applicant's invention, which, generally stated, consists in a device capable of carrying out the objects above set forth, in the novel parts and combinations of parts disclosed and defined in the appended claims.
